The main raw material which is brass with copper alloy (CuZn39Pb3) is shaped with the process of hot forging and die casting, after this it is transferred to various machine tools and CNC machines by the order of machining processing. These products which have been processed have the operation of sanding polishing and chrome plating . After this process they are sent to the assembling unit for the assembling process.
During the work process, the quality control department staff controls the processing of the products using some certified calibration measuring instruments ( various types of tooth gauges, calipers and micrometers ) which will prevent the products to be defected.
In the assembling stage 100 % controls are accomplished for the function and pressure flow rates. The armatures ( taps , mixers ) are tested with 8 bar for pressure with water and with 5 bar are tested with air for non leakage. All products manufactured by us are endured to a pressure of 25 bar.<<
The raw material of the armatures are brass which have 59 % copper, 39 % zinc, 1 % of lead contents. The manufacturing method of armatures is die casting. The armature bodies are manufactured with brass ingots in melting pots which are used to melt the ingots followed with the process of die casting in its machines, the valves and tap bodies are shaped in the process of brass bars been cut with coping saws in different sizes followed by hot forging.
Later on machining, polishing, chrome plating and assembling stages are done in order. Before going for packaging all products are tested once again for 100 % non – leakage, flow of water and eye control, thus this will prevent defected products to be sent to customers.
Our laboratory experiment tests and works are in accordance with the legal autority or institution. The laboratory management system is based in Gül Pres Döküm San.A.Ş – Bakir Pirinc San. Sitesi, Sardunya Cad. Beylikduzu – Istanbul Turkey. Apart from the above mentioned address there is no other particular connection in a temporary or itinerant institution which have other experiments / works.<<<
